Description

Apparatus and method for supporting management of electronic component container

The technology disclosed herein relates to a technology for mounting electronic components on a circuit board, and particularly to a technology for managing a container for electronic components.

Mounting machine is known. The mounting machine is a device that mounts electronic components on a circuit board. A plurality of types of electronic components are supplied to the mounting machine according to the production item. Usually, the electronic component is supplied to the mounting machine in a form accommodated in a reel or a tray. A reel and a tray are a kind of container that houses a plurality of electronic components. Each container (reel, tray, or other container) contains a specific type of electronic component, and a plurality of containers are set in the mounting machine according to the production item.

Regarding the above, Japanese Patent Application Laid-Open No. 2005-175017 describes a setup operation for setting a plurality of containers on a mounting machine according to a production item, and a technique for supporting the setup operation.

When one production lot is completed, one or more electronic components remain in each container set in the mounting machine. Accordingly, among the containers set in the mounting machine, those to be reused in the next production lot can be left set in the mounting machine without being removed from the mounting machine. Thereby, it is only necessary to replace the minimum container, and the setup work for the next production lot can be facilitated.

However, some electronic components are called MSD (Moisture Sensitive Device) and have a characteristic of deteriorating by absorbing moisture. Such an electronic component has a predetermined floor life and needs to be mounted on a circuit board before the floor life is exhausted. Here, the floor life is a kind of index indicating the expiration date of the electronic component, and means a period in which the electronic component can withstand an environment of a predetermined humidity or higher. While the container is set on the mounting machine, the remaining floor life of the electronic components in the container decreases. Therefore, if the container to be reused in the next production lot is left set in the mounting machine, the floor life of the electronic component may be exhausted before the next production lot is completed.

In view of the above problems, the present specification provides a technology that facilitates the setup work of the mounting machine while considering the floor life.

The technique disclosed in the present specification uses the container database and the production plan database to determine a management mode suitable for the electronic component container. In the container database, the type, the remaining number, and the remaining floor life time of the electronic components housed in the container are recorded. In the production plan database, the type and number of required electronic components and the scheduled start time of the production lot are recorded for each production lot scheduled for the mounting machine. By using the information recorded in these databases, it is possible to determine whether or not the electronic components remaining in the container are used up by the mounting machine before the floor life is exhausted. When it is judged that the floor life of an electronic component is not exhausted, as a suitable management mode, for example, a management mode in which the container is left set in the mounting machine or stored in the vicinity of the mounting machine. You can choose. On the other hand, when the floor life is exhausted, as a suitable management mode, for example, management of storing the container in a moisture-proof environment, performing a baking process on the electronic component, or discarding the electronic component Aspects can be selected. Which management mode is selected can be appropriately determined in consideration of available equipment, cost of electronic components, and other factors.

As an embodiment of the present technology, the present specification discloses an apparatus that supports management of a container that houses a plurality of electronic components supplied to a mounting machine. This support device is required for each storage lot database that records the type, remaining number, and remaining floor life of the electronic components stored in the storage body, and for each production lot scheduled for the mounting machine.

The figure which shows an example of the production plan table contained in a production plan database. The figure which shows an example of the mounting program table contained in a production plan database. The figure which shows an example of a reel database. The flowchart which shows the process which the processing apparatus of a management computer performs.

In one embodiment of the present technology, it is preferable that the processing unit calculates a first scheduled time when the mounting machine uses up the electronic component accommodated in the container. Furthermore, it is preferable that the processing means determines a management mode suitable for the container based on whether or not the first time from the current time to the first scheduled time is shorter than the remaining time of the floor life.

In the above-described embodiment, when the first time is shorter than the remaining time of the floor life, the processing means is a management mode in which the container is stored at or near the mounting machine as a management mode suitable for the container. Can be selected. This is because even if the container is not stored in a moisture-proof environment, the mounting machine can use up all the electronic components before the floor life of the electronic components is exhausted.

In the above-described embodiment, when the first time is longer than the remaining floor life, the processing unit may further calculate a second scheduled time when the mounting machine starts using the electronic component housed in the housing body. preferable. Furthermore, it is preferable that the processing means determines a management mode suitable for the container based on whether or not the second time from the second scheduled time to the first scheduled time is shorter than the remaining time of the floor life.

In the above-described embodiment, when the second time is shorter than the remaining floor life, the processing unit selects a management mode for storing the container in a moisture-proof environment as a management mode suitable for the container. can do. If the container is stored in a moisture-proof environment, the time when the electronic component floor life is exhausted can be delayed, and the electronic component remaining in the container can be used up before the floor life of the electronic component is exhausted.

In the above-described embodiment, it is preferable that the container database further records the recovered floor life when the electronic component housed in the container is subjected to a process of recovering the floor life. In this case, when the second time is longer than the remaining time of the floor life, the processing means is based on whether or not the second time is shorter than the floor life to be recovered. Is preferably determined.

In the above-described embodiment, when the processing time is shorter than the floor life in which the second time is restored, the processing means restores the floor life to the electronic component housed in the housing body as a management mode suitable for the housing body. It is possible to select a management mode for performing processing. This is because if the electronic parts are processed to recover the floor life, the electronic parts remaining in the container can be used up before the recovered floor life of the electronic parts is exhausted.

In the above-described embodiment, when the processing means is longer than the floor life in which the second time is recovered, the management mode is such that the electronic component accommodated in the container is discarded as a management mode suitable for the container. Can be selected.

In the above-described embodiment, the process for restoring the floor life can be a baking process.

In one embodiment of the present technology, it is preferable that the support device further includes an acquisition unit that acquires the identification information assigned to the container. In this case, the container database preferably records container data including the type of electronic component, the remaining number, and the remaining floor life time for each piece of identification information of the container. Furthermore, it is preferable that when the acquisition unit acquires the identification information, the processing unit determines a management mode suitable for the container using the container data associated with the identification information.

Referring to the drawings, a mounting system that is an embodiment of the present technology will be described. The mounting system of the present embodiment is a system for mounting an electronic component 18 on a circuit board 28 to produce an electronic circuit used in an electronic device. As shown in FIG. 1, the mounting system includes a mounting machine 10, a reading device 40, and a management computer 50. The reading device 40 is a so-called bar code reader and can read information recorded on the bar code. The management computer 50 is configured to be able to communicate with the mounting machine 10 and the reading device 40.

The mounting machine 10 is a device for mounting the electronic component 18 on the circuit board 28. The mounting machine 10 is also referred to as a surface mounting machine or a chip mounter. The mounting machine 10 is provided side by side with a solder printer, another mounting machine, and an inspection device, and constitutes a series of mounting lines. The mounting machine 10 includes a mounting head 14 and a plurality of component supply devices 26 that supply electronic components 18 to the mounting head 14. The plurality of component supply devices 26 are arranged in a direction perpendicular to the paper surface of FIG. 1, and therefore, only one component supply device 26 is shown in FIG. Each component supply device 26 is detachably attached to the stage 30 of the mounting machine 10. The mounting head 14 is supported by the mobile robot 12, and transports and places the electronic component 18 supplied from the component supply device 26 to a mounting position on the circuit board 28.

The reel 24 is attached to the component supply device 26. The reel 24 accommodates a plurality of electronic components 18 on the wound carrier tape 20. The component supply device 26 supplies the electronic components 18 to the mounting head 14 one by one by feeding the carrier tape 20 by a predetermined amount. In the mounting machine 10, it is necessary to supply a plurality of types of electronic components 18 to one production item (that is, one circuit board 28). Therefore, the reels 24 of a plurality of types of electronic components 18 are set in a plurality of component supply devices 26 according to the production items. Each reel 24 has a barcode 22 for recording identification information. The barcode 22 may be an RFID, a two-dimensional code, and other information recording elements.

In the mounting machine 10, when one production lot is completed, a setup operation for the next production lot is performed. In this setup operation, for example, the reel 24 set in the mounting machine 10 is replaced according to the production item of the next production lot. Here, when one production lot is completed, one or a plurality of electronic components 18 usually remain on each reel 24 set in the mounting machine 10. Accordingly, among the plurality of reels 24 set in the mounting machine 10, those that are reused in the next production lot can be left set in the mounting machine 10 without being removed from the mounting machine 10. . Thereby, only the minimum reel 24 needs to be replaced, and the setup work for the next production lot can be facilitated.

However, some of the electronic components 18 are called MSD (Moisture Sensitive Device) and have a characteristic of being deteriorated by absorbing moisture. Such an electronic component 18 has a predetermined floor life, and must be mounted on the circuit board 28 before the floor life is exhausted. Here, the floor life is a kind of index indicating the expiration date of the electronic component 18, and means a period in which the electronic component 18 can withstand an environment of a predetermined humidity or higher. While the reel 24 is set in the mounting machine 10, the remaining floor life of the electronic component 18 in the reel 24 is reduced. Therefore, if the reel 24 to be reused in the next production lot is left set in the mounting machine 10, the floor life of the electronic component 18 may be exhausted before the next production lot is completed. is there.

In view of the above problems, the mounting system according to the present embodiment incorporates a support device that teaches the worker how to manage each reel 24 in consideration of the floor life of the electronic component 18. Hereinafter, the configuration and function of the support apparatus will be described with reference to the drawings.

As shown in FIG. 2, the support device is configured using a display device 16, a reading device 40, and a management computer 50 of the mounting machine 10. The management computer 50 includes a processing device 52 and a storage device 54. The storage device 54 can store a production plan database 56 and a reel database 58. The processing device 52 is communicably connected to the storage device 54, and determines a management mode suitable for the reel 24 using the production plan database 56 and the reel database 58. The management mode determined by the processing device 52 is transmitted to the mounting machine 10, displayed on the display device 16, and taught to the operator.

The production plan database 56 includes a production plan table shown in FIG. 3 and a mounting program table shown in FIG. As shown in FIG. 3, the production plan table includes, for each production lot (A column), the type (B column), production quantity (C column), start time (D column) of the circuit board 28 to be produced, The end time (E column) and other information are recorded. On the other hand, as shown in FIG. 4, a mounting program table is prepared for each type of circuit board 28, and each mounting program table includes a mounting time (I) in the mounting order (H column). Column), the type of electronic component 18 to be mounted (J column), the mounting position on the circuit board 28 (K column), and other information. Note that the production plan database 56 of this embodiment includes two tables, a production plan table and an implementation program table, but the production plan database 56 includes one table that integrates the production plan table and the implementation program table. But you can. Alternatively, the production plan database 56 may record information recorded in the production plan table and the implementation program table in three or more tables.

As shown in FIG. 5, in the reel database 58, for each piece of identification information (M column) assigned to the reel 24, the type of electronic component 18 (N column) accommodated and the remaining number (O Column), the remaining floor life of the electronic component 18 (P column), the floor life recovered by the baking process (Q column), and the identification information (R column) of the feeder set.

FIG. 6 shows the flow of processing executed by the processing device 52. By executing this processing flow, the processing device 52 can determine a management mode suitable for the reel 24 and teach it to the operator. In step S <b> 12, the operator reads the barcode 22 attached to the reel 24 using the reading device 40. Usually, when one production lot is completed, it is preferable to read the barcode 22 of the reel 24 set in the mounting machine 10, but the present invention is not limited to this.

When the reading device 40 reads the barcode 22, the identification information of the reel 24 recorded on the barcode 22 is transmitted from the reading device 40 to the management computer 50. When receiving the identification information of the reel 24, the processing device 52 of the management computer 50 proceeds to the next step S14. The identification information of the reel 24 may be automatically transmitted from the mounting machine 10 to the management computer 50 when one production lot is completed without using the reading device 40. Further, the operator may read a barcode (not shown) attached to the component supply device 26 instead of the barcode 22 of the reel 24.

In step S <b> 14, the processing device 52 uses the received identification information of the reel 24 (or the component supply device 26) and the reel database 58 to determine the type, remaining number, and floor life of the electronic components 18 accommodated in the reel 24. Get the remaining time. Next, in step S16, using the production plan table (see FIG. 3) in the production plan database 56, the earliest production lot (column A) in which the electronic component 18 accommodated in the reel 24 is used is specified. The type (B column), production quantity (C column), start time (D column), end time (E column), and other information of the circuit board 28 in the production lot are acquired.

In step S18, the processing device 52 calculates the first scheduled time using the information acquired in steps S14 and S16. Here, the first scheduled time means a scheduled time when the mounting machine 10 uses up the electronic components remaining on the reel 24. For example, it is assumed that 100 electronic components “PT001” remain on the reel 24. Referring to the mounting program table of FIG. 4, it can be seen that the electronic component “PT001” is used for the production (mounting) of the circuit board “CB0001”. Furthermore, by referring to the mounting program table, it is possible to know the time required to produce one circuit board “CB0001” and the number of electronic components “PT001” used in the production of one circuit board “CB0001”. From the production plan table shown in FIG. 3, it can be seen that production of the circuit board “CB0001” starts at 9:00. As an example, if the required time is 6 seconds and the number of uses is 1, the first scheduled time can be calculated as 9:10. The processing device 52 may calculate the first scheduled time using other information recorded in the production plan database 56 and / or the reel database 58. The calculation method of the first scheduled time is not particularly limited.

In step S20, the processing device 52 determines whether or not the first time from the current time to the first scheduled time is shorter than the remaining floor life time acquired in step S14. When the first time is shorter than the remaining time of the floor life, the process proceeds to step S22. Otherwise, the process proceeds to step S24.

In step S22, the processing device 52 selects a management mode for storing in the mounting machine 10 or in the vicinity thereof as a management mode suitable for the reel 24. When the first time described above is longer than the remaining time of the floor life of the electronic component 18, the mounting machine 10 does not store all the reel 24 before the floor life of the electronic component 18 is exhausted without storing the reel 24 in a moisture-proof environment. This is because the electronic component 18 can be used up. The management mode selected by the processing device 52 is transmitted to the mounting machine 10 and displayed on the display device 16 of the mounting machine 10. The display device 16 can display, for example, “keep set” or “store on nearby shelf”. Thereafter, the processing device 52 returns to Step S12.

On the other hand, in step S24, the processing device 52 calculates the second scheduled time. Here, the second scheduled time means a scheduled time at which the mounting machine 10 starts using the electronic component 18 remaining on the reel 24. The processing device 52 of the present embodiment refers to the production plan table (see FIG. 3) in the production plan database 56, and extracts the production lot start time (column D) identified in step S16 as the second scheduled time. . Note that the processing device 52 may calculate the second scheduled time using other information recorded in the production plan database 56 and / or the reel database 58. The method for calculating the second scheduled time is not particularly limited.

In step S26, it is determined whether or not the second time from the second scheduled time to the first scheduled time is shorter than the remaining floor life time acquired in step S14. When the second time is shorter than the remaining time of the floor life, the process proceeds to step S28. Otherwise, the process proceeds to step S26.

In step S28, the processing device 52 selects a management mode for storing the reel 24 in a moisture-proof environment as a management mode suitable for the reel 24. If the reel 24 is stored in a moisture-proof environment, the time when the floor life of the electronic component 18 in the reel 24 is exhausted can be delayed. If the second time described above is longer than the remaining time of the floor life of the electronic component 18, if the reel 24 is stored in a moisture-proof environment until the second scheduled time, the floor life of the electronic component 18 is exhausted. In addition, the mounting machine 10 can use up all the electronic components 18. The management mode selected by the processing device 52 is transmitted to the mounting machine 10 and displayed on the display device 16 of the mounting machine 10. On the display device 16, for example, “store in a moisture-proof environment” can be displayed. Thereafter, the processing device 52 returns to Step S12.

On the other hand, in step S30, the processing device 52 refers to the reel database 58 (FIG. 5) and acquires the floor life (Q column) recovered by the baking process for the electronic component 18 accommodated in the reel 24. Then, the processing device 52 determines whether or not the second time described above is shorter than the recovered floor life. When the second time is shorter than the floor life to be recovered, the process proceeds to step S32. Otherwise, the process proceeds to step S34.

In step S32, the processing device 52 selects a management mode for performing the baking process on the electronic component 18 accommodated in the reel 24 as a management mode suitable for the reel 24. This is because if the electronic component 18 is baked, the electronic component 18 remaining on the reel 24 can be used up before the recovered floor life of the electronic component 18 is exhausted. The management mode selected by the processing device 52 is transmitted to the mounting machine 10 and displayed on the display device 16 of the mounting machine 10. The display device 16 can display, for example, “perform baking process”. Thereafter, the processing device 52 returns to Step S12.

On the other hand, in step S34, the processing device 52 selects a management mode for discarding the electronic component 18 accommodated in the reel 24 as a management mode suitable for the reel 24. This is because, even if the electronic component 18 is baked, the mounting machine 10 cannot use up the electronic component 18 remaining on the reel 24. The management mode selected by the processing device 52 is transmitted to the mounting machine 10 and displayed on the display device 16 of the mounting machine 10. For example, “discard” can be displayed on the display device 16. Thereafter, the processing device 52 returns to Step S12.

The operator can know the management mode suitable for each reel 24 by sequentially reading the barcode 22 of each reel 24 set in the mounting machine 10. The worker can efficiently perform the setup work for the next production lot based on the taught management mode. When the replacement work of the reel 24 (or the component supply device 26) is performed by the device, the management mode determined by the management computer 50 may be taught to the device.

Although specific examples of the present invention have been described in detail above, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.

For example, in the present embodiment, the management mode of the reel 24 that accommodates the plurality of electronic components 18 has been described. However, the technique described in the present embodiment manages the tray that accommodates the plurality of electronic components 18 and other containers. The same applies to the embodiment.

Further, in this embodiment, when the reading device 40 reads the barcode 22 on the reel 24, the processing (see FIG. 6) for teaching a management mode suitable for the reel 24 is executed using the barcode 22 as a trigger. However, the trigger of the process for teaching the management mode is not limited to this. As another embodiment, the mounting system automatically executes processing for teaching a management mode for one or a plurality of reels 24 set in the mounting machine 10 when one production lot is completed. It may be. Usually, what kind of reels 24 are set in the mounting machine 10 is known in advance by the mounting machine 10, the management computer 50, or other devices. Therefore, it is not always necessary to acquire the identification information of the reel 24 by the reading device 40.

The technical elements described in the present specification or drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.
